Given that 44 million people travel through both sets of departure gates, it is inevitable that some bits and bobs will be left behind in the frenzy to cross airside, but more than 50 bars of Palmolive soap?

A Russian vinyl pressing of Dark Side of the Moon? A Dyson vacuum cleaner? A welding mask? People, what are you thinking? And how big do you think the overhead luggage rack is?

There are the usual suspects: trays and trays of Dr Dre's, a lather of laptops, a blind horizon of Ray Bans, stuff that can be forgotten in the seat pocket of a plane, or haphazardly left when the boarding call comes.

There is also a sea of grog and a stink of perfumes. But a raft? Did someone not trust the safety instructions? And a metre-high zebra. It's not as if you could miss it.

The airport auction has been a regular feature on the Sydney penny pinchers circuit since 2013, but one genre, beyond the grog and the sunnies seems to be ever present Australiana.

Be it a saucy stubbie holder, where a stern adult has gaffa taped across the nipples, or a selection of substandard boomerangs, Australiana always features heavily.

Every year, you are guaranteed to dive your hand into the brightly coloured lucky dip and pull out a kangaroo scrotum coin purse. It seems that for many, it seemed like a good idea at the time. Until they got to the gate.

Every lot on the block starts for a buck, so if you'd be keen to pick up a Louis Vuitton bag, or a similar model by his illegitimate stepbrother Louie Vitone, the auction takes place online through Pickles Auctioneers.
